What is made up of 2 protons and 2 neutrons?
In terms of radioactivity it is an alpha particle.
What could be in the higs Boson?
The Higgs Boson, if it exists, should be a massive point particle, so there should be nothing "in" it.
Does electron mean a subatomic particle with a negative charge?
Electrons are negatively charged subatomic particles, but have almost no mass. The mass of an electron is about 1/2000 that of a proton or neutron. The neutron is the most massive of the subatomic particles at 1.6755 x 10-24 grams.
What is the the heat source of the mantle?
radioactivity
Which property of loose earth materials most likely increases as particle size decreases?
capillarity
What subatomic particle is the least and most massive and which subatomic particle is respectively?
least - electron most - the top quark
Is alpha particle the slowest?
For a given amount of energy, yes. Because its the most massive.
What is made up of 2 protons and 2 neutrons?
In terms of radioactivity it is an alpha particle.
What particle in an atom is the least massive?
electron
What particle is least massive?
The least massive principle atomic particle is the electron. Neutrons and protons are much more massive and are about equal in mass. Of course, there are even smaller particles such as quarks which are less massive than even electrons.
Why do alpha particle have higher ionizaion energy than beta particle?
Alpha particles are far more massive. Alpha particle is an (ionized) helium atom, a beta particle is just an electron.
Most massive particles in an atom?
99.9% of an atom's mass is concentrated in the nucleus, with protons and neutrons having almost the same mass, with neutrons being slightly higher. So your question would be, 'What atom has the most protons and neutrons combined?' And that answer is Nobelium. Nobelium has 102 protons and 160 neutrons which makes it the most 'massive' atomic particle, even more so then Lawrencium which has 103 protons but only 159 neutrons. Of course, in a few months, we could have a new, more massive element.
What particle in the atom is the least massive?
least - electron most - the top quark
What is helime?
Do you mean helium? An inert ("noble") gas, atomic number 2. An alpha particle (as in radioactivity) is a helium nucleus.
What is matter on the atomic level?
The most massive fundamental particle proven to exist is the top quark, by a lot. It has approximately the mass of a rhenium atom.The most massive non-quark fundamental particle known to exist is the Higgs boson, which has about the same mass as a caesium atom.The most massive atom officially recognized by IUPAC is Copernicium (atomic number 112, atomic mass about 285).
How massive is a alpha particle?
an alpha particle is made of two protons and 2 neutrons. its basically the same as the nucleus of a helium atom
Who discovered radioactivity?
henri bacquerel discovered radioactivity in 1896.Artificial radioactivity was first discovered by Joliot Curie and her husband in 1934 while studying the effect of alpha particle bombardment on like elements like Aluminium
